FIELD OF THE INVENTION

This invention relates to a UZM-35 composition comprising a MSE zeolite, an MFI zeolite, and an ERI zeolite. The UZM-35 composition is represented by the empirical formula of:

M_(m) ^(n+)R⁺ _(r)Al_(1-x)E_(x)Si_(y)O_(z)

where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as dimethyldipropylammonium and E is a framework element such as gallium.

BACKGROUND OF THE INVENTION

Zeolites are crystalline aluminosilicate compositions which are microporous and which are formed from corner sharing AlO₂ and SiO₂ tetrahedra. Numerous zeolites, both naturally occurring and synthetically prepared are used in various industrial processes. Synthetic zeolites are prepared via hydrothermal synthesis employing suitable sources of Si, Al and structure directing agents such as alkali metals, alkaline earth metals, amines, or organoammonium cations. The structure directing agents reside in the pores of the zeolite and are largely responsible for the particular structure that is ultimately formed. These species balance the framework charge associated with aluminum and can also serve as space fillers. Zeolites are characterized by having pore openings of uniform dimensions, having a significant ion exchange capacity, and being capable of reversibly desorbing an adsorbed phase, which is dispersed throughout the internal voids of the crystal without significantly displacing any atoms, which make up the permanent zeolite crystal structure. Topological zeolite structure are described in Atlas of Zeolite Framework Types, which is maintained by the International Zeolite Association Structure Commission at http://www.iza-structure.org/databases/. Zeolites can be used as catalysts for hydrocarbon conversion reactions, which can take place on outside surfaces as well as on internal surfaces within the pore.

One particular zeolite of the MSE structure type, designated MCM-68, was disclosed by Calabro et al. in 1999 (U.S. Pat. No. 6,049,018). This patent describes the synthesis of MCM-68 from dication directing agents, N,N,N′,N′-tetraalkylbicyclo[2.2.2]oct-7-ene-2R,3S:5R,6S-dipyrrolidinium dication, and N,N,N′,N′-tetraalkylbicyclo[2.2.2]octane-2R,3S:5R,6S-dipyrrolidinium dication. MCM-68 was found to have at least one channel system in which each channel is defined by a 12-membered ring of tetrahedrally coordinated atoms and at least two further independent channel systems in which each channel is defined by a 10-membered ring of tetrahedrally coordinated atoms wherein the number of unique 10-membered ring channels is twice the number of 12-membered ring channels.

Applicants have successfully prepared a new family of material compositions designated UZM-35 composition. The topology of one of the zeolites in the composition is similar to that observed for MCM-68. The materials are prepared via the use of a simple commercially available structure directing agents, such as dimethyldipropylammonium hydroxide, in concert with small amounts of K⁺ and Na⁺ together using the Charge Density Mismatch Approach to zeolite synthesis described in U.S. Pat. No. 7,578,993. The UZM-35 zeolite having the MSE topology may be synthesized as a UZM-35 composition comprising the MSE topology zeolite as well as a MFI topology zeolite and an ERI topology zeolite. Topologies of MSE, MFI, ERI are as defined in Atlas of Zeolite Framework Types, which is maintained by the International Zeolite Association Structure Commission at http://www.iza-structure.org/databases/.

The crystalline microporous zeolitic UZM-35 composition described above, may be synthesized by forming a reaction mixture containing reactive sources of M, R, Al, Si and optionally E and heating the reaction mixture at a temperature of about 150° C. to about 200° C., or about 165° C. to about 185° C., for a time sufficient to form the composition, the reaction mixture having a composition expressed in terms of mole ratios of the oxides of:

aM₂O:bR_(2/p)O:1-cAl₂O₃ :cE₂O₃ :dSiO₂ :eH₂O

where “a” has a value of about 0.05 to about 1.25, “b” has a value of about 1.5 to about 40, “p” is the weighted average valance of R and varies from 1 to about 2, “c” has a value of 0 to about 1.0, “d” has a value of about 4 to about 40, “e” has a value of about 25 to about 4000. The MSE type zeolite UZM-35 zeolite is synthesized along with additional zeolites MFI and ERI to form the UZM-35 composition.

Yet another embodiment of the invention is a hydrocarbon conversion process using the UZM-35 composition. The process comprises contacting the hydrocarbon with the UZM-35 composition at conversion conditions to give a converted hydrocarbon.

DETAILED DESCRIPTION OF THE INVENTION

Applicants have prepared an aluminosilicate zeolitic composition which comprises a MSE zeolite, a MFI zeolite, and an ERI zeolite. The MSE zeolite has a topological structure that is related to MSE as described in Atlas of Zeolite Framework Types and thus will be called an MSE zeolite herein. As will be shown in detail, the UZM-35 composition is different from MCM-68 in a number of its characteristics. The microporous crystalline zeolitic UZM-35 composition has an empirical composition in the as-synthesized form and on an anhydrous basis expressed by the empirical formula:

M_(m) ⁺R⁺ _(r)Al_(1-x)E_(x)Si_(y)O_(z)

where M represents a combination of potassium and sodium exchangeable cations. R is a singly charged organoammonium cation, examples of which include but are not limited to the dimethyldipropylammonium cation (DMDPA⁺), dimethyldiisopropylammonium (DMDIP⁺), choline [(CH₃)₃N(CH₂)₂OH]⁺, ETMA⁺, DEDMA⁺, trimethylpropylammonium, trimethylbutylammonium, dimethyldiethanolammonium, methyltripropylammonium, TEA⁺, TPA⁺ and mixtures thereof and “r” is the mole ratio of R to (Al+E) and varies from about 0.25 to about 2.0 while “m” is the mole ratio of M to (Al+E) and varies from about 0.05 to about 3. The mole ratio of silicon to (Al+E) is represented by “y” which varies from about 2 to about 30. E is an element which is tetrahedrally coordinated, is present in the framework and is selected from the group consisting of gallium, iron and boron. The mole fraction of E is represented by “x” and has a value from 0 to about 1.0, while “z” is the mole ratio of O to (Al+E) and is given by the equation:

z=(m·n+r+3+4·y)/2.

Where M is only one metal, then the weighted average valence is the valence of that one metal, i.e. +1 or +2. However, when more than one M metal is present, the total amount of:

M_(m) ^(n+)=M_(m1) ^((n1)+)+M_(m2) ^((n2)+)+M_(m3) ^((n3)+)+ . . .

and the weighted average valence “n” is given by the equation:

$n = \frac{{m_{1} \cdot n_{1}} + {m_{2} \cdot n_{2}} + {m_{3} \cdot n_{3}} + \ldots}{m_{1} + m_{2} + m_{3} + \ldots}$

The microporous crystalline zeolitic UZM-35 composition is prepared by a hydrothermal crystallization of a reaction mixture prepared by combining reactive sources of M, R, aluminum, silicon and optionally E. The sources of aluminum include but are not limited to aluminum alkoxides, precipitated aluminas, aluminum metal, aluminum salts and alumina sols. Specific examples of aluminum alkoxides include, but are not limited to aluminum ortho sec-butoxide and aluminum ortho isopropoxide. Sources of silica include but are not limited to tetraethylorthosilicate, colloidal silica, precipitated silica and alkali silicates. Sources of the E elements include but are not limited to alkali borates, boric acid, precipitated gallium oxyhydroxide, gallium sulfate, ferric sulfate, and ferric chloride. Sources of the M metals, potassium and sodium, include the halide salts, nitrate salts, acetate salts, and hydroxides of the respective alkali metals. R is an organoammonium cation selected from the group consisting of dimethyldipropylammonium, choline, ETMA, DEDMA, TEA, TPA, trimethylpropylammonium, trimethylbutylammonium, dimethyldiethanolammonium and mixtures thereof, and the sources include the hydroxide, chloride, bromide, iodide and fluoride compounds. Specific examples include without limitation dimethyldipropylammonium hydroxide, dimethyldipropylammonium chloride, dimethyldipropylammonium bromide, dimethyldiisopropylammonium hydroxide, dimethyldiisopropylammonium chloride, dimethyldiisopropylammonium bromide ethyltrimethylammonium hydroxide, diethyldimethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, and tetrapropylammonium chloride.

Note that during synthesis, the metal M is +1 valance, specifically potassium and sodium. However, in an alternative embodiment, the composition may undergo additional ion exchange steps post synthesis to provide a material with one or more metals, M, having a +2 valance.

The reaction mixture containing reactive sources of the desired components can be described in terms of molar ratios of the oxides by the formula:

aM₂O:bR_(2/p)O:1-cAl₂O₃ :cE₂O₃ :dSiO₂ :eH₂O

where “a” varies from about 0.05 to about 1.25, “b” varies from about 1.5 to about 40, “c” varies from 0 to 1.0, “d” varies from about 4 to about 40, and “e” varies from about 25 to about 4000. If alkoxides are used, it is preferred to include a distillation or evaporative step to remove the alcohol hydrolysis products. The reaction mixture is now reacted at a temperature of about 150° C. to about 200° C., about 165° C. to about 185° C., or about 170° C. to about 180° C., for a period of about 1 day to about 3 weeks and preferably for a time of about 5 days to about 12 days in a sealed reaction vessel under autogenous pressure. After crystallization is complete, the solid product is isolated from the heterogeneous mixture by means such as filtration or centrifugation, and then washed with deionized water and dried in air at ambient temperature up to about 100° C. It should be pointed out that UZM-35 zeolite seeds can optionally be added to the reaction mixture in order to accelerate the formation of the composition.

A preferred synthetic approach to make UZM-35 composition utilizes the charge density mismatch concept, which is disclosed in U.S. Pat. No. 7,578,993 and Studies in Surface Science and Catalysis, (2004), Vol. 154A, 364-372. The method disclosed in U.S. Pat. No. 7,578,993 employs quaternary ammonium hydroxides to solubilize aluminosilicate species, while crystallization inducing agents such as alkali and alkaline earth metals and more highly charged organoammonium cations are often introduced in a separate step. Once some UZM-35 seeds have been generated using this approach, the seeds can be used in a single step synthesis of the UZM-35 composition, using, for example, a combination of dimethyldipropylammonium hydroxide and the alkali cations. The use of commercially available dimethyldipropylammonium hydroxide to prepare the UZM-35 composition offers a great economic advantage over the structure directing agents previously employed (N,N,N′,N′-tetraalkylbicyclo[2.2.2]oct-7-ene-2R,3S:5R,6S-dipyrrolidinium dication, and N,N,N′,N′-tetraalkylbicyclo[2.2.2]octane-2R,3S:5Rs,6-dipyrrolidinium dication) to prepare aluminosilicates with the MSE topology. Additionally, dimethyldipropyl ammonium hydroxide can be employed as the hydroxide or the chloride in concert with other inexpensive organoammonium hydroxides using the charge density mismatch concept to reduce costs even further.

The UZM-35 composition, which is obtained from the above-described process, is characterized by the x-ray diffraction pattern using the Rietveld refinement method described in J. Appl. Cryst. (1969) 2, 65-71, and having at least the d-spacings and relative intensities set forth in Table A below.

As synthesized, the UZM-35 composition will contain some of the exchangeable or charge balancing cations in its pores. These exchangeable cations can be exchanged for other cations, or in the case of organic cations, they can be removed by heating under controlled conditions. Because UZM-35 composition comprises large pore zeolite(s), it is also possible to remove some organic cations directly by ion exchange. The UZM-35 composition may be modified in many ways to tailor it for use in a particular application. Modifications include calcination, ion-exchange, steaming, various acid extractions, ammonium hexafluorosilicate treatment, or any combination thereof, as outlined for the case of UZM-4M in U.S. Pat. No. 6,776,975 B1 which is incorporated by reference in its entirety. Properties that are modified include porosity, adsorption, Si/Al mole ratio, acidity, thermal stability, etc.

The UZM-35 compositions which are modified by one or more techniques described in the '975 patent (herein UZM-35HS) are described by the empirical formula on an anhydrous basis of:

M1_(a) ^(n+)Al_((1-x))E_(x)Si_(y′)O_(z′)

where M1 is at least one exchangeable cation selected from the group consisting of alkali, alkaline earth metals, rare earth metals, ammonium ion, hydrogen ion and mixtures thereof, “a” is the mole ratio of M1 to (Al+E) and varies from about 0.05 to about 50, “n” is the weighted average valence of M1 and has a value of about +1 to about +3, E is an element selected from the group consisting of gallium, iron, boron, and mixtures thereof, “x” is the mole fraction of E and varies from 0 to 1.0, y′ is the mole ratio of Si to (Al+E) and varies from greater than about 4 to virtually pure silica and z′ is the mole ratio of O to (Al+E) and has a value determined by the equation:

z′=(a·n+3+4·y′)/2

By virtually pure silica is meant that virtually all the aluminum and/or the E metals have been removed from the framework. It is well know that it is virtually impossible to remove all the aluminum and/or E metal. Numerically, a zeolite is virtually pure silica when y′ has a value of at least 3,000, preferably 10,000 and most preferably 20,000. Thus, ranges for y′ are from 4 to 3,000 preferably greater than 10 to about 3,000; 4 to 10,000 preferably greater than 10 to about 10,000 and 4 to 20,000 preferably greater than 10 to about 20,000.

In specifying the proportions of the zeolite starting material or adsorption properties of the zeolite product and the like herein, the “anhydrous state” of the zeolite will be intended unless otherwise stated. The term “anhydrous state” is employed herein to refer to a zeolite substantially devoid of both physically adsorbed and chemically adsorbed water.

The crystalline zeolitic UZM-35 composition of this invention can be used for separating mixtures of molecular species, removing contaminants through ion exchange and catalyzing various hydrocarbon conversion processes. Separation of molecular species can be based either on the molecular size (kinetic diameter) or on the degree of polarity of the molecular species.

The UZM-35 composition of this invention can also be used as a catalyst or catalyst support in various hydrocarbon conversion processes. Hydrocarbon conversion processes are well known in the art and include cracking, hydrocracking, alkylation of both aromatics and isoparaffin, isomerization of paraffin and poly-alkylbenzenes such as xylene, trans-alkylation of poly-alkybenzene with benzene or mono-alkybenzenes, disproportionation of mono-alkybenzenes, polymerization, reforming, hydrogenation, dehydrogenation, transalkylation, dealkylation, hydration, dehydration, hydrotreating, hydrodenitrogenation, hydrodesulfurization, methanation and syngas shift process. Specific reaction conditions and the types of feeds which can be used in these processes are set forth in U.S. Pat. No. 4,310,440 and U.S. Pat. No. 4,440,871 which are hereby incorporated by reference. Preferred hydrocarbon conversion processes are those in which hydrogen is a component such as hydrotreating or hydrofining, hydrogenation, hydrocracking, hydrodenitrogenation, hydrodesulfurization, etc.

Hydrocracking conditions typically include a temperature in the range of about 204° C. to about 649° C. (400° to 1200° F.) or about 316° C. to about 510° C. (600° F. and 950° F.). Reaction pressures are in the range of atmospheric to about 24,132 kPa g (3,500 psig), or between about 1379 to about 20,685 kPa g (200 to 3000 psig). Contact times usually correspond to liquid hourly space velocities (LHSV) in the range of about 0.1 hr⁻¹ to 15 hr⁻¹, preferably between about 0.2 and 3 hr⁻¹. Hydrogen circulation rates are in the range of 178 to about 8,888 std. m³/m³ (1,000 to 50,000 standard cubic feet (scf) per barrel of charge), or about 355 to about 5,333 std. m³/m³ (about 2,000 to about 30,000 scf per barrel of charge). Suitable hydrotreating conditions are generally within the broad ranges of hydrocracking conditions set out above.

The reaction zone effluent is normally removed from the catalyst bed, subjected to partial condensation and vapor-liquid separation and then fractionated to recover the various components thereof. The hydrogen, and if desired some or all of the unconverted heavier materials, are recycled to the reactor. Alternatively, a two-stage flow may be employed with the unconverted material being passed into a second reactor. Catalysts of the subject invention may be used in just one stage of such a process or may be used in both reactor stages.

Catalytic cracking processes are preferably carried out with the UZM-35 composition using feedstocks such as gas oils, heavy naphthas, deasphalted crude oil residua, etc. with gasoline being the principal desired product. Temperature conditions of about 454° C. to about 593° C. (about 850° F. to about 1100° F.), LHSV values of 0.5 to 10 and pressure conditions of from about 0 to about 344 kPa g (about 0 to 50 psig) are suitable.

Alkylation of aromatics usually involves reacting an aromatic (C₂ to C₁₂), especially benzene, with a monoolefin to produce a linear alkyl substituted aromatic. The process is carried out at an aromatic:olefin (e.g., benzene:olefin) ratio of between 1:1 and 30:1, a olefin LHSV of about 0.3 to about 10 hr⁻¹, a temperature of about 100° to about 250° C. and pressures of about 1379 kPa g to about 6895 kPa g (about 200 to about 1000 psig). Further details on apparatus may be found in U.S. Pat. No. 4,870,222 which is incorporated by reference.

Alkylation of isoparaffins with olefins to produce alkylates suitable as motor fuel components is carried out at temperatures of −30° to 40° C., pressures from about atmospheric to about 6,895 kPa (1,000 psig) and a weight hourly space velocity (WHSV) of 0.1 to about 120. Details on paraffin alkylation may be found in U.S. Pat. No. 5,157,196 and U.S. Pat. No. 5,157,197, which are incorporated by reference.

The following examples are presented in illustration of this invention and are not intended as undue limitations on the generally broad scope of the invention as set out in the appended claims.

The structure of the UZM-35 composition of this invention was determined by x-ray analysis. The x-ray patterns presented in the following examples were obtained using standard x-ray powder diffraction techniques. The radiation source was a high-intensity, x-ray tube operated at 45 kV and 35 ma. The diffraction pattern from the copper K-alpha radiation was obtained by appropriate computer based techniques. Flat compressed powder samples were continuously scanned at 2° to 56° (2θ). Interplanar spacings (d) in Angstrom units were obtained from the position of the diffraction peaks expressed as θ where θ is the Bragg angle as observed from digitized data. Intensities were determined from the integrated area of diffraction peaks after subtracting background, “I_(o)” being the intensity of the strongest line or peak, and “I” being the intensity of each of the other peaks.

As will be understood by those skilled in the art the determination of the parameter 2θ is subject to both human and mechanical error, which in combination can impose an uncertainty of about ±0.4° on each reported value of 2θ. This uncertainty is, of course, also manifested in the reported values of the d-spacings, which are calculated from the 2θ values. This imprecision is general throughout the art and is not sufficient to preclude the differentiation of the present crystalline materials from each other and from the compositions of the prior art. In some of the x-ray patterns reported, the relative intensities of the d-spacings are indicated by the notations vs, s, m, and w which represent very strong, strong, medium, and weak, respectively. In terms of 100×I/I_(o), the above designations are defined as:

w=0-15; m=15-60: s=60-80 and vs=80-100

In certain instances the purity of a synthesized product may be assessed with reference to its x-ray powder diffraction pattern. Thus, for example, if a sample is stated to be pure, it is intended only that the x-ray pattern of the sample is free of lines attributable to crystalline impurities, not that there are no amorphous materials present.

In order to more fully illustrate the invention, the following examples are set forth. It is to be understood that the examples are only illustration and are not intended as an undue limitation on the broad scope of the invention as set forth in the appended claims.
